The family pharmacist says this medication is rarely used and very expensive. My father (83) has advanced Parkinsons that is progressing quickly. He was diagnosed just two and a half years ago and is advanced already with a 24 hour caregiver. Walking is a thing of the past and now swallowing and chocking is my concern. He has a supra catheter as well as he is totally incontinent.
As to the cost, if it were something that would miraculously make Dad become mobile again, and able to eat without choking, I would say no cost is too high. That's just me, though.
